DEVIHC E" F UTILIZING WAVE-POWER.

SPECIFICATION forming part of Letters Patent N 0. 706,558, dated August12, 19012. Application filed March 12, 1902. Serial No. 97,935. (Nomodel.)

To (tZZ whom it may concern.-

Be it known that we, JOHN C. HERGENHAN and CHARLES O.V N DER Ann,citizens of the United States, residing at New York city, in the countyof New York and State of New York, have invented certain new and usefulImprovements in Devices for Utilizing Wavelower; and we do declarethefollowing to be a full, clear, and exact description of the in- IQvention, such as will enable others skilled in the art to which itappertains to make anduse the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to new and useful improvements in tide-motorpowers; and it consists in the provision of a float adapted to ride uponthe surface of Water and carrying mechanism which isadap'ted to rotate ashaft as the float rises and lowers with the moving surface of theWater, said float being anchored to a weight by a cable which passesabout suitable winding-drums and connected to a weight which isadaptedto be hoisted as the float rises, thuscausing the winding-d rumto rotate and drive apulley or balance-wheel on which the power may betransferred at a suitable location. v The invention relates,further,tovarious details of construction, which will be hereinaf,-,

ter more fully described and then specifically defined in the appendedclaims.

The invention is illustrated in the accompanying drawings, which, withthe letters of reference marked thereon, form a part of thisapplication, and in'which drawings- Figure 1 is a perspective viewofthetop of shaft B, journaled in a suitable frame carried by the float,is a gear-wheel G, which rotates With said shaft, and on the end of the0nd winding-drum E.

surfaceof the float.

Fig. 2 is avertical rotate with said ratchet-Wheel on the shaft E,

and loosely journaled on the shaft E is a sec- The teeth of thegearwheel mounted on the shaft E are in mesh with the teeth of thepinion on the shaft B.

Mounted to have a vertically-movable play between the standards M,mounted on the float, is a weight N, which is preferably grooved on itsOpposite faces to receive the guide strips O on theinner faces of saidstandards. Connected tosaid weight is a cable Q, which passes over apulley Q, which is journaled on a stub-shaft R, carried at the upperends of said standards. horizontally from the cross-piece S at the topsof the standards are bracket-arms S, carrying a shaft T, on which apulley T is journaled, over which said cable passes. Said cable afterpassing over the pulleys at the upper endof the standard winds about thedrum E, which isloosely" journaled on the shaft E, and thence passesabout a pulley J, which is journaled horizontally on the upper The cableafter passing about the pulley J .winds about the drum K and passesthence to the anchor, comprising 'a Weight (not shown)which is adaptedto rest upon the bedof' the stream or the ground un .derneath thewaterover which the float is dis- The operation of our device will be.at once understood and is as follows: The anchor being sunken the cableis adjusted the proper length so thatwhen the float isrestinghorizontally the weight carried by the float is adjacent to itslowest limit and when the float is raised by the action of the waves thecable becomes taut and is held taut, and the suspended weight iselevated on the upward,

movement of the float by means of the rope Projecting being held tautand anchored at its lower end. This movement of the weight as the floatrises will cause the drum K, about which the rope winds, to rotate in adirection to drive the gear-wheel held thereto by the pawl in onedirection, and as the float lowers such sliding weight mounted on thestandards will fall by gravity, and the drum K will turn idly upon itsshaft, and on a succession of rising and lowering motion of the float acontinuous rotary or slight intermittent motion will be imparted to thedriving-wheel in one direction. The power thus generated may betransmitted from the driving-whee] to any location desired, theessential feature of the invention consisting of the means, asdescribed, for producing a rotary movement to the. drivingshaft by meansof the mechanism described. Having thus fully described our invention,what we claim as new, and desire to secure by Letters Patent, is

1. A tide-motor power comprising a float,a windin g-drum and shaft withgear-wheels rotating therewith and mounted upon said float, an anchor, asuspended weight carried by the float, a cable adapted for connection tosaid anchor, passing about said drum, and over suitable pulleys andsuspending said weight, whereby 'as the float rises said suspendedweight will be raised and cause the drivingshaft to be operated, as setforth.

2. A tidemotor power comprising a float, a shaft, a winding-drum loosely.journaled on said shaft and mounted upon the float, a ratchet-wheelfastened to rotate with said drum, a gear-wheel keyed to rotate withsaid shaft,fa pawl carried by the gear-wheel and designed to engage saidratchet-wheel, a counter-shaft carried by the float, a pinion-wheelkeyed thereto and meshing with said gearwheel, a cable, adapted forconnection at one end to an anchor, and passing about said winding-drum,and pulleys carried by the float, a weight suspended on uprights carriedby the float and to which suspended weight said cable is connected, asshown and for the purpose set forth.

3. A tide-motor power comprising in combination with a float,a shaft journaled therein, a pinion-wheel rotating with said shaft, acounter-shaft, a gear-wheel meshing with said pinion,drums on the counter-shaft,a horizontallymounted pulley on the float, standards on saidfloat provided with guide-strips on their adjacent faces, a suspendedweight having grooves on its opposite faces to receive saidguide-strips, pulleys at the upper ends of the standards, a cablefastened to said suspended weight passing about said pulleys and drums,and its other end adapted for attachment to an anchor, substantially asshown and described.

In testimony whereof we hereuntoaflix our signatures in presence of twowitnesses.
